Bluetooth ni tekshirish

▶ Android ilovalarida Bluetooth funksiyasidan foydalanish uchun AndroidManifest.xml faylida quyidagi 2 ta permissions ko‘rsatilishi lozim:

permission
android:name="android.permission.BLUETOOTH"/>

▶ Activity da esa quyidagi sinf ob’ekti yaratiladi:

BluetoothAdapter bluetoothAdapter;
static final int REQUEST_ENABLE_BT = 0;


▶ Ushbu BluetoothAdapter sinfining ob’ekti getDefaultAdapter() metodi orqali initsializatsiya qilinadi:
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
▶ Joriy qurilmada Bluetooth ni borligini tekshirish uchun BluetoothAdapter ob’ektini null qiymatga quyidagicha tekshirib ko‘ramiz:
private boolean IsBluetoothAvailable() { if (bluetoothAdapter == null) return false;
else
return true;


}
▶ Agar Bluetooth mavjud bo‘lsa, uni yoqish uchun isEnabled() metodidan foydalaniladi
isEnabled() metodidan foydalanish

if (IsBluetoothAvailable()) {

if (!bluetoothAdapter.isEnabled()) {
Intent i = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
